1031 Exchange
IRC §1031 allows real property investors to defer capital gains taxes and depreciation recapture indefinitely by reinvesting proceeds from a sale into like-kind replacement property. For ultra-high-net-worth investors, the strategy extends well beyond the basics, Delaware Statutory Trusts, reverse exchanges, improvement exchanges, and 1031-to-Opportunity Zone transitions unlock structural flexibility unavailable to the typical investor.
How a §1031 Exchange Works
Without a §1031 exchange, the sale of appreciated real property triggers federal capital gains tax (0%, 15%, or 20% depending on income), the §1411 net investment income tax (3.8%), unrecaptured §1250 depreciation at 25%, and potentially state capital gains taxes. For a California resident selling a $10 million property with a $7 million gain, the combined federal and state tax liability can approach 40% of the realized gain, nearly $2.8 million.
A §1031 exchange defers all of that tax. The proceeds from the relinquished property are transferred to a qualified intermediary (QI) at closing, the taxpayer never touches the funds. The investor then has 45 days to identify potential replacement properties and 180 days to close on them. If the exchange is properly structured, no gain is recognized at the time of sale.
The gain doesn't disappear, it is embedded in the carryover basis of the replacement property. But the deferral of $2.8 million in taxes, invested at 7% over 20 years, creates an additional $10.8 million of compounding wealth. That is the compounding power of deferral.

Advanced Structures for Ultra-High-Net-Worth Investors
Delaware Statutory Trusts (DSTs)
For investors who want to exit active management, DSTs offer the ideal 1031 solution. A DST is a legal entity that holds institutional real estate, Class A multifamily, net-leased medical offices, industrial logistics centers, and issues fractional beneficial interests to investors. Under Rev. Rul. 2004-86, those interests constitute like-kind real property for §1031 purposes. DSTs allow precise reinvestment matching (no leftover 'boot'), provide professional management, offer geographic and sector diversification, and give investors the economic benefits of institutional real estate without operational responsibilities.
Reverse Exchanges
A reverse exchange allows the investor to acquire the replacement property before selling the relinquished property, reversing the traditional sequence. This is valuable in competitive real estate markets where desirable replacement properties must be locked in immediately. Under Rev. Proc. 2000-37, the replacement property is parked with an Exchange Accommodation Titleholder (EAT) for up to 180 days while the investor arranges sale of the relinquished property. Reverse exchanges require precise structuring and significant capital (the investor must fund the replacement acquisition without relying on sale proceeds).
Improvement Exchanges
When available replacement properties require significant renovation, an improvement exchange (or 'construction exchange') allows exchange proceeds to be used for improvements on the replacement property during the exchange period. The QI holds both the replacement property and the improvement funds, commissioning construction on the investor's behalf. The property is then transferred to the investor at 180 days with the qualifying improvements included in the 'like-kind' property received.
1031 into Opportunity Zones
Proceeds from a 1031 exchange are not eligible for the Opportunity Zone deferral, §1031 and §1400Z-2 cannot both apply to the same gain simultaneously. However, a taxable sale of real property can generate a capital gain that is then invested in a Qualified Opportunity Fund, while separately, a different property sale is structured as a §1031 exchange. Multi-property investors can strategically route individual sales to each program based on which property and gain profile each strategy optimizes.
Critical Timelines: No Exceptions
Proceeds must be wired directly to the qualified intermediary. Any constructive receipt by the taxpayer disqualifies the exchange.
Written identification of replacement property delivered to QI. No extensions under any circumstances. Missing this deadline voids the exchange.
Must close on identified replacement property. The exchange period ends on the earlier of 180 days or the due date of the tax return for the year of sale.
Is a 1031 Exchange Right for You?
A sophisticated long-term planning strategy: execute successive 1031 exchanges throughout your lifetime, deferring all gain. At death, IRC §1014 provides a step-up in basis to fair market value, eliminating all embedded deferred gain. Heirs inherit the property at its current value with zero capital gains liability on the appreciation. Combined with proper estate planning, this approach can permanently eliminate capital gains tax across generations.
